AWNING.

Application filed January 22, 1926. Serial No. 83,117.

This invention relates to new and useful improvements in awnings for window openings and the like, and the object of the invention is to provide an awning which will be simple to manufacture, easy to erect in position, and'which will allow at all times free passage of air, through the openings to which it is fitted.

Another object is to provide a collapsible awning which will be easily adjusted to suit weather conditions or raised to clear the opening when required. I i

In my invention, I provide adjustable guides which may be secured to the side frames of a window, door or the like. Slidably mounted on the guides are the curtain supports which each consist of a bent bar, pivotally mounted on a horizontally disposed bar, the ends of which are bent in the form of loops surrounding the guides. The curtains are made of flexible material such as duck, linen, cotton or the like and are so attached to the supports that the lower curtains may be raised and partially covered by the curtain immediately above them when the awning is in the closed position when not in use. Means are provided for spacing the V curtains at predetermined distances from one another when in the open position, and means are provided for holding the curtain in shape when the awning is in the closed or open position.

In the drawings which illustrate one form of my invention,

Referring more particularly to the drawings, designatesthe side frames, 21 the linteland 22 the sill of a window. Secured to the side frames and in close proximity to the lintel are the brackets 23, the preferred detail of which is shown in Figures 8 and 9. The horizontally disposed portion 24 of the bracket 23 is provided with three apertures 25, 26 and 27, while bolts, screws, or such like fastening means may be placed through'the apertures 28 formed in the vertically disposed portion 29. The lower guide brackets 30, shown in detail in Figures 10 and 11, may be secured in any suitable manner to the side frames in close proximity to the sill of the window. An aperture 3i is formed in the horizontally disposed .section of each of the brackets and suitable bolt or screw holes 32 are formed in the vertically disposed sections 33. 'The brackets 23 and 30, secured to "each side frame, are so positioned that the holes or apertures and 31 are in alignment and spaced from the side frame. Secured to the upper brackets and extending downward- 1y therefrom parallel with the side frames.

are the guides 34, the lower ends 35 of which,

pass through the apertures '36 formed in the tensioning screws 37, which may be formed of bars threaded at one end, bent and guides are the horizontally'disposed rods 38,

the ends of which are bent in the form of a loop to enclose thesaid guides. Four curtains are shown in the drawing and three rods 38 are required to form the support for the upper edges of the three lower curtains while rod 39 forms a support for the upper edge of the uppermost curtain. Pivotally attached to the rods 38, and near the ends thereof, are the members 40. These members 40, form supports for the lower edges of the three upper curtains and hold said curtain edges projecting outwardly from the window frame, in the manner shown 1n Figure 7. The support 41 for the lower edge of the lowermost curtain is of substantially the same formation as the members 40, but its ends are looped to encircle the guides. Flexible ties 42 are provided between the rods 38, the upper end of each tie being secured to the rod 39 so that when the awning is in the open position,said rods will be held at a predetermined distance apart. Struts 42 may be placed between the ends of the lowermost curtain support and the ends of the lowermost rod 38. The curtains are made with side portions 40 of substantially triangular formation, one edge of each of which is stitched or otherwise secured to the main body 41 of the curtain, which may be of rectangular formation, as shown in Figure 4. The upper edge 51 of each curtain is secured to the horizontally disposed rod 38, or to the rod 39, while the lowermost edges of the side portions and the main body portions of the curtain is stitched or otherwise secured to the curtain supports. A fringe 43 may be attached to the lowermost edges of the curtain or said edge may extend over supports and may be scalloped, as shown in Figures 4, 6 and 7. Secured to the brackets 28, are the pulley shackles 44, part of which may pass through the apertures 27. One of these shackles 44 may be provided with two rotatably mounted pulleys 45, while the other shackle 44 may be provided with a single rotatably mounted pulley 46. passed partially around one of the pulleys 45 and is secured at one end to the lowermost rod 38. Another rope 48 may be passed partially around the other pulley 45, and then taken over pulley 46 and secured to the opposite end of the lowermost rod 38. The free ends of the ropes 47 and 48 may be knotted together so that they may move in unison when raising the awning. A suitable hook or cleat 49, may be attached to the side frames to provide a securing means for the ropes. Suitable stiffeners 50 may be placed between the rods 38 or 39 and the curtain supports 40, and these stiffener-s may be preferably placed near the sides of the curtains. Compression springs 52 may be mounted on the guides near the upper end thereof and may be held in position by any suitable means in close proximity to the brackets 23.

Modifications may be made in the construction of the device without departing from the spirit of the invention.

In operation the device is very simply erected by securing the guide brackets in position, threading the flexible guides through Rope 47 is or otherwise slidably securing the ends of the rods 38, securing the guides to the brackets 23, and to the tensioning screws 37, and pulling on the tensioning screws by tightening or revolving the nuts 51.. The upper rod 39 is slipped into position. The curtains are secured to the rods 38 and 39, and also to the curtain supports. The ropes are secured to the lowermost rod and are passed over the pulleys 45 and46. hen the awning is in use, the curtains are spaced from one another and are held in predetermined relationship to one another by means of the tying members and the struts. Air may pass through between the curtains, that is between the curtain supports and the rods 38, and also between each pair of rods 38. Strong lights will not penetrate the curtains when the awning is in the extended or open posi- 7 tion. To close the awning the ropes 47 and 48 are pulled, thereby raising the lowermost curtain. This curtain is held in shape by means of the strut or stabilizer between the lowermost curtain support and the lowermost rod 38. The remaining curtains rest on the lowermost curtain as it is raised towards the top of the window or opening over which the awning is fitted. The compression springs 52 form a cushioning means when raising the awning and a starting means for lowering the awning.

The device provides an easily fitted and operated awning for shading windows or the like without materially interfering with the passage of air and light into the opening over which it is fitted.

Having thus described my invention, what I claim is 7 An awning structure for windows comprising upper brackets secured to the side frames of the window in close proximity to the lintel, lower brackets secured to the side frames in alignment with the upper brackets and in close proximity to the sill of the window, adjusting screws carried by the lower brackets, flexible guide strands stretched between said adjusting screws and the upper brackets, coil springs encircling the upper portions of said strands in close proximity to the lower surfaces of the upper brackets, a plurality of horizontal members extending between said guide strands and having their terminals bent to form eyes receiving said strands therethrough, a U-shaped curtain support carried by each of said horizontal members and having the terminals thereof bent to form eyes adapted to receive loosely one of said horizontal members therethrough, a further U-shaped curtain support having the terminals thereof bent to form eyes receiving the guide strands therethrough, struts connecting the last mentioned curtain support to the adjacent horizontal memher, and a further horizontal member carried by the uppermost bracket for cooperation with the adjacent curtain support, a brackets and also around one of the pair of pair of pulleys carried by one of the upper pulleys carried by the remaining upper 10 brackets, 21 single pulley carried by the rebracket and the other flexible element being maining upper bracket, flexible elements attrained around the remaining pulley of the tached at one end to opposite terminal porlastmentioned bracket.

tions of the lowermost horizontal member, In Witness whereof, I have hereunto set my one of said elements being trained around hand.
